在美国vps的vue中自定义指令的方法有以下两种

vue自定义指令语法：

Vue.directive(id, definition)

1.自定义全局指令

Vue.directive(‘focus’, {

bind: function (el) {

el.focus()

},

inserted: function (el) {

el.focus()

},

updated: function () {

}

});

2.自定义私有指令

directives: {

‘fontweight’: {

bind: function (el, bingding) {

el.style.fontWeight = bingding.value;

}

},

‘fontsize’: function (el, bingding) {

el.style.fontSize = parseInt(bingding.value) + ‘px’;

}

}
